Preferably, the swing arm assembly 30 is elastically connected with the base 10 through an elastic assembly 40 or the two swing arms 31 are elastically connected through the elastic assembly 40;

In the initial state, the elastic assembly 40 makes the two swing arms 31 at the closed position, when the rider rides the scooter, the gravity center is adjusted for the first time to make the front side of the base 10 downward and the two swing arms 31 overcome the tension of the elastic assembly 40 to open, the rider adjusts the gravity center for the second time to make the front side of the base 10 upward, at this time, the restoring force of the elastic assembly 40 makes the two swing arms 31 return to the closed position to realize the movement of the scooter, which is favorable for making the movement of the scooter smoother.

In this embodiment, the swing arm assembly 30 is elastically connected to the base 10 through an elastic assembly 40, as shown in fig. 3, the elastic assembly 40 includes a torsion spring, which is sleeved on the hinge shaft 313, and two ends of the torsion spring are respectively abutted to the swing arm 31 and the hinge seat 11. In other embodiments, the two swing arms 31 may be interconnected by a resilient assembly 40, or the swing arms 31 may be connected to the base by springs.

Preferably, the other ends of the swing arms 31 extend obliquely downward to the movable universal wheels 33, respectively, to be supported on a plane. Since the front side of the base 10 needs to reserve enough space for movement, a large gap exists between the front side of the base 10 and the plane, in order to ensure that the movable universal wheel 33 can be supported on the plane, in this embodiment, the other ends of the two swing arms extend obliquely downward to the position where the movable universal wheel 33 is supported on the plane.

In other embodiments, the swing arm may also be arranged horizontally, as long as the mobile gimbal 33 is capable of supporting on a flat surface.

In this embodiment, preferably, the base 10 is gradually inclined upward from back to front, the swing arm 31 is mounted on the front side of the base 10, and the front side level of the base 10 is lifted, so that enough movable space is reserved for the base 10 and the swing arm 31. In other embodiments, the base 10 is disposed horizontally, so long as enough space is reserved below the base 10 for moving up and down.

In this embodiment, the handle bars 60 are distributed on the front side of the seat 50, the seat 50 is mounted on the base 10 through the first connecting member 70, and the seat 50 is mounted on the front side of the base 10 through the first connecting member 70, so that the effort is saved when the rider rides on the scooter to adjust the center of gravity.

The handle bar 60 is mounted on the base 10 through a second connecting piece 80, so that the handle bar 60 extends to the front side of the seat 50, a rider can conveniently sit forward on the seat 50 and hold the handle bar with hands, preferably, the second connecting piece 80 is a U-shaped rod, one end of the U-shaped rod is connected with the handle bar 60, and the other end of the U-shaped rod is connected with the upper end surface of the base 10, so that the front side of the base 10 can be synchronously driven to move downwards by pressing the handle bar 60, and the labor is saved.

In this embodiment, the swing arm 31 includes a swing arm body 311, a hinge seat 11 is disposed on the base 10, one end of the swing arm body 311 is hinged to the hinge seat 11 through a hinge shaft 32, two opposite sides of the hinge shaft 32 at one end of the swing arm body 311 are respectively provided with an elastic sheet 312 and a limiting sheet 313, the elastic sheet 312 and the limiting sheet 313 respectively support against the hinge seat 11, and the swing arm body 311 overcomes elastic tension of the elastic sheet 312 to open and close.

The elastic sheet 312 and the limiting sheet 313 enable the swing arm body 311 to be limited in a forward state, and preferably, after the two swing arms 31 rotate to a closed state due to the fact that the limiting sheet 313 does not have elasticity, the limiting sheet 313 can prevent the two swing arms 31 from continuing to be closed inwards, so that the closed state position of the two swing arms 31 is limited in the forward state.

Of course, the present utility model is not limited to the above-described embodiments, and those skilled in the art can make equivalent modifications and substitutions without departing from the spirit of the present utility model, and these equivalent modifications and substitutions are included in the scope of the present utility model as defined in the appended claims.
